This invention relates to-a mechanism in writingmachines for inserting and adjusting front feed sheets in front of a foundation sheet in the front sheets to desired lines, and line selection means having indicator numerals corresponding to the lines of the front feed sheets, according to U. S. Patent No. 2,086,945 issued July 13, 1937.

Ihe object of the present invention is to improve mechanism of the above kind and to make it possible to insert and adjust a-plurality of front feed sheets for simultaneously typing on different lines. According to the present invention this result is achieved by providing the selection means with two sets of indicator numerals corresponding to the lines of the front feed sheets, said sets being movable relatively to each other.

A mechanism embodying the invention is illustrated by way of example in the drawings in which Fig. 1 is a front elevation of the device in initial position, Figs. 2 and 3 are similar views showing the mechanism in different positions during its actuation, and Fig. 4 is a section on line 4-4 of Fig. 3.

In the mechanism illustrated in the drawings there is mounted on the non-feed portion 4 of the paper carriage of a typewriter, in which the platen roller S is rotatably supported about its axis 6ll, a frame consisting. mainly of the members 2, l, 21, this frame being removable,

The frame can rock in the paper carriage portion 6 about pins 2a. The frame carries funnel shape guides 8, 9 located above the platen roller S in theirposition of rest. These guides 8, 9 direct a to hold and guide the foundation sheet J which is usually lapped around the platen roller S along with a carbon sheet. The paper guide l6, holds the front feed sheet, at its front end, which sheet is guided and advanced-between guides 8, "9, 9a

and the feed rolls l1, l8, and contacts with the platen roller S and the foundation sheet J at the typing line 61, at the level of the printing place of the types 68, the sheet being guided under the lower surface of the platen roller, below the paper guide P and thepress roll 62, and thence to the rear. The feed rolls ll, l8carried by shafts 19, 20 are rotatably mounted in the frame 2, I, 21 by means of arms 29, 24. One of these arms 23, 24 is capable of rocking in the frame. By means of a spring 25 arranged between the arms 23, 24 the feed rolls I 1; l8 are pressed one against the other. By means of a holding member 69 and a hand lever lll'the feed rolls can be separated from each other against the action of the spring 25.

The rotation of the feeds rolls l1, I8 is effected by means of the shaft l9, the bevelwheels 34, 35, the vertical shaft 33, and gears, notshown, from an actuating member which in the illustrated instance consists of a rotary disk 29. The actuating or control member 29 is connected to a line selection means for effecting a selective rotation of the feed rolls l1, l8 and to feed the front sheet to a desired line. This selection means comprises a number of manipulative holds 261: inthe form of finger holes marked with symbols, preferably numerals, corresponding to the lines of the front feed sheet. In' the illustrated example numerals 1-to 26 are providedcorresponding to 26 writing lines on each front feed sheet. The number of lines may obviously be reduced sheet employed. The front feed nated by references K and K.

In addition to the set of symbols consisting of the num-beredflngerholes- 2912, there is provided a further set 66 of symbolsalso corresponding to the lines of the front feed sheets K K 6 These two sets of symbols can be moved relatively to each other, the second set 66 consisting of numbers arranged on a separate disk 65. The disk 65 does not follow the feed movements of the actuating means 29 It isflxed coaxially with the actuating means 29, by means of a screw. 28a

arranged in theaxis of rotation of the actuating disk 29 and attaching the disk to-the part 21 of the frame 2, 1, 21. l l

The arrangement of the disk 65 with the set of symbols 66 thereon, relatively to the actuating disk 29 and the set of symbols 2% connected thereto, is suchthat in the initial position of the actuating disk 29, the corresponding symbols of the two sets 29b, 66 exactly register with each other. The disk 65 is so fixed that upon loosening the screw 28a it can be turned to permit ad- 'justment in order to obtain the exact register of the two sets 29b and 66 in the initial position of the actuating disk 29. By tightening the screw 28a the disk 25 can be retained in its exactly adjusted position.

.The actuating disk 29 is under the action of a spring 290 which is diagrammatically shown in Fig. 1. This spring corresponds to the respective part 38 of the Patent Specification 2,086,945 but it is compressed for being disposed to straighten.

One end of this spring 29c is secured to the shaft 28, the other end being linked to the bolt 29d of the disk 29. Against the action of this spring 290, the disk 29 can be rotated clockwise from the initial position of Fig. 1 by dialling it by a finger of' the operator inserted in one of the finger holes 29b. By employing the finger hole corresponding to the symbol, the disk is brought Preferably the disk 65 is formed as a cover plate for the spring 290 engaging the actuating disk- 29 and rotating the same about its axis in counterclockwise direction. This provides a simple mounting of the second set of symbols B6 and an improvement of the appearance of the mechanism.

The operation of the mechanism will now be described by means of the following example.

The foundation sheet J is assumed to be already in the machine and is further held above the platen roller S by means of press rolls H which are preferably resiliently mounted in the frame 2, 1, 21. In front of this foundation sheet there are inserted two front feed sheets K and K which are to be written both at different lines simultaneously. The entries made on the top sheet are transmitted preferably by means of inserted carbon paper sheets to the second sheet and the foundation sheet. The front feed sheets may consist for example of account cards. In modern bookkeeping it frequently occurs. that certain entries which are to be totalled on a foundation sheet, have to be booked into different accounts and therefore must be typed on different account cards.

The two front feed sheets K and K constitute such different account cards which usually contain entries extending over a number of lines, which are not always the same in both sheets. In the present case for example the card K is already typed up to line 9, and the card K up to line 19. The next free line on which a new entry is to be made is line on card K and line 20 on card K I The card K is first inserted in the funnel formed by the guides 8, 9 so that it is gripped at its lower end by the feed rolls l1, Hi. The operator selects, for dialling the actuating disk 29 by a finger, the finger hole 291) designated by the numeral l9, and by this means rotates the actuating disk 29 in clockwise direction until the numeral 10 on the said disk registers with the numeral 20 on the fixed disk or stationary member 65, as shown in Fig. 2. This actuation of the disk 29 results in rotation of the feed rolls H, It by a certain amount. on withdrawing the finger.

the actuating disk '29 and the feed rolls l1, I! are retained in the position of Fig. 2 by the pawl mechanism which is provided behind the disk29 in the same manner as specified in the Patent 2,086,945, as already mentioned.

Then the second card K is inserted between a the guides 8, 9 until its lower end is gripped by the said rolls 11, H3. The rotation of the actuating disk 29 in clockwise direction is now completed by the finger of the operatorinserted in the same finger hole I!) as before until the finger is arrested by the dialling stop 30, and finally released from the actuating disk 29. In this rotation of the actuating disk 29 the two cards K and K are moved together from the position of the Fig. 2intothe position of Fig. 3 whereby the line 10 of the card K and the line 20 of the card K arrive in position of. registration with the typing line 61 of the foundation sheet J, and can now be typed together. After typing on the adjusted line, the two cards Kl and K can be advanced along with the foundation sheet J by one or more lines so that further entries can be made on all the sheets in one or more further lines. This further feeding takes place by actuating the hand lever 44, which is movable in two directions,

as may be recognised from the Patent Specification 2,086,945. By lifting the said lever the disk 29 is released by steps, advancing thus the cards K and K 'from one line to the followingone. By lowering the lever 44, however, the above mentioned pawl mechanism is disengaged. The disk 29 being at once wholly released rotates along in the clockwise direction under the action of the spring 290 back into the initial position of Fig. 1 together with the feed rolls l1, l8. Both cards K and K are thus automatically ejected. The

second card K can be inserted either in front of or behind the card K On inserting the card K between the guides 8, 9 the finger of the operator does not have to be fully removed from the selected and already actuated finger hole of the disk 29, which in the present instance is designated by the numeral lli'. It is sufiicient, after the finger hole with the numeral 10 has been brought intoregistration with the numeral 20 of the disk 65, to allow a slight yielding of the finger whereby the actuating disk 29 is brought by the action of the spring motor against the corresponding pawl of the pawl mechanism and is held in the adjusted position.

As shown in the Patent Specification 2,086,945, the lever 44 may also be actuated by means of the line spacing device of the machine.

The mechanism according to the present invention thus-permits rapid and simultaneous insertion of. the two sheets K and K to different lines so that they can then be typed together in one and the same operation. This permits a substantial simplification in booking entries, and a shortening of the'time heretofore required for such bookkeeping operations. Obviously the application of the invention is not limited to typingaccount cards and a foundation sheet. The mechanism according to the invention can be used also inall other bookkeeping and typing operations in which a plurality of sheets are to be typed simultaneously at different commercial writing machine.
